“Some day...after I am dead, you may perhaps come to learn the right and wrong of this. I cannot tell you.”
Explanation:
This statement by Mr Utterson shows his uncompromising loyalty for his friend. <u>He knows that his friend has gone rogue but still supports hi to death and grave dangers that he is to face because of it.</u>
<u>He says that his loyalty is so absolute that only when he is gone Mr Jekyll will be able to see where he is going wrong</u> because as long as he is there he will protect him from the harm that he will bring upon himself without telling him about it. 
 
        
             
        
        
        
A predicate is the part of a sentence that contains a verb wich tells something about the subject.
Now, in simple present or present progressive the formula is: subject + verb+ complement; the verb is the predicate. Taking the first three example, the subject is circled and the verb verbs comes after.
Answers are underlined:
The West Indian Manatee <u>is large a sea mammal.</u> 
Manatte <u>rest just below the water's surface.</u> 
Sea grass <u>is one of their favorite things</u> to eat. 
In the last one it can't be eat the predicate because the predicate refers always to the subject, and 'sea grass doesn't eat'. "To eat is a complement"
